Ade, not sure what you mean by "throttle setting" but here's my setup:
AUW = 80g = 2.8 oz (includes lipo)
Hobbyking HK1612-KV3200 - this is a 7.4V motor but I run it of 3.7v
4x2.5 prop
This gives me 6W power
I find that for launches, especially if it's breezy, to use full power and as soon as I've launched then back the power of a little depending on the rate of climb and strength of breeze.
I'm contemplating adding some weight in the cabin and going up to 2S, which will require me to change the esc. I've read somewhere someone doing this sort of thing which helped the model penetrate into the breeze better.
I'm no expert on these things but I guess if you aim for a 2S setup you'll have a wider range of power or "throttle setting" to play with. I'm sure someone on the forum could provide additional insight.
